Signed-off-by: Linus Lüssing <linus.luessing(a)c0d3.blue> Signed-off-by: Sven Eckelmann <sven(a)narfation.org> Signed-off-by: Simon Wunderlich <sw(a)simonwunderlich.de> commit cd0c2051ddd5274db345352070b3799d70672de6 Author: Linus Lüssing <linus.luessing(a)c0d3.blue> Date: Tue Jun 11 22:58:40 2019 +0200 batman-adv: mcast: detect, distribute and maintain multicast router presence To be able to apply our group aware multicast optimizations to packets with a scope greater than link-local we need to not only keep track of multicast listeners but also multicast routers. With this patch a node detects the presence of multicast routers on its segment by checking if /proc/sys/net/ipv{4,6}/conf/<bat0|br0(bat)>/mc_forwarding is set for one thing. This option is enabled by multicast routing daemons and needed for the kernel's multicast routing tables to receive and route packets. For another thing if a bridge is configured on top of bat0 then the presence of an IPv6 multicast router behind this bridge is currently detected by checking for an IPv6 multicast "All Routers Address" (ff02::2). This should later be replaced by querying the bridge, which performs proper, RFC4286 compliant Multicast Router Discovery (our simplified approach includes more hosts than necessary, most notably not just multicast routers but also unicast ones and is not applicable for IPv4). If no multicast router is detected then this is signalized via the new BATADV_MCAST_WANT_NO_RTR4 and BATADV_MCAST_WANT_NO_RTR6 multicast tvlv flags.

The function can work or not, but the code logic should never do something different based on this. Because we don't care if debugfs works or not, this trickles back a bit so we can clean things up by making some functions return void instead of an error value that is never going to fail.

Which means we sign up for all traffic for ff02::1/128 and 224.0.0.0/24. When the node itself had IPv6 enabled or joined a group in 224.0.0.0/24 itself then so far this would result in a multicast TT entry which is redundant to the WANT_ALL_UNSNOOPABLES. With this patch such redundant TT entries are avoided.

Just holding it during the checks and updates of the bat_priv stored multicast flags and mla_list is enough. Therefore this patch splits batadv_mcast_mla_tvlv_update() in two: batadv_mcast_mla_flags_get() at the beginning of the worker to gather and calculate the new multicast flags, which does not need any locking as it neither reads from nor writes to bat_priv->mcast. And batadv_mcast_mla_flags_update() at the end of the worker which commits the newly calculated flags and lists to bat_priv->mcast and therefore needs the lock.
